Precautions for rackmounting
This device is guaranteed to operate at an ambient temperature
of 0 to 40 °C. If this device is mounted in an EIA rack together
with other devices, heat from the various devices may cause the
temperature inside the rack to rise, rendering this device unable
to perform to its full potential. To ensure that heat does not
accumulate inside this device, please ensure that the following
conditions are met when rack-mounting it.
• If you plan to mount this device together with devices that
tend to generate heat, such as power amps other than XMV
series products, allow 1U or more of vacant space between
this device and other devices. Also attach ventilation panels
in this space or leave them open to ensure sufficient ventilation.
• Leave the back of the rack open, and allow at least 10 cm of
space between the rack and the wall or ceiling to ensure sufficient ventilation. If the back of the rack cannot be left open,
provide forced air cooling for the rack, for example by
installing a commercially available fan kit. If you install a
fan kit, leaving the back of the rack closed may provide more
effective cooling. For details, refer to the owner’s manual
provided with the rack or fan kit.

o [YDIF] connectors
These connectors are used to make a ring connection with
the devices that comprise the MTX system, allowing digital
audio signals to be transmitted and received. Use CAT5e or
better Ethernet STP cables (shielded twisted pair cables) that
have all eight pins connected in a straight connection. The
maximum cable length between devices is 30 meters, and
you can connect up to eight devices that are equipped with
the [YDIF] connectors. For details, refer to the MTX Editor
User’s Manual.
!0 [ST IN] connectors
These are unbalanced RCA phono jacks for inputting analog
audio signals from a CD player or other device.
!1 [INPUT]/[OUTPUT] connectors
These are balanced input/output connectors for analog audio
input and output. Connect line level devices or microphones
to the [INPUT] connectors, and line level devices to the
[OUTPUT] connectors. The [INPUT] connectors provide
head amps, and can also provide +48V phantom power.
MTX Editor is used to specify the gain of the internal head
amps and to turn the phantom power on/off.
Use the included Euroblock plugs to make connections (see
“Euroblock plug connection” on page 12 for details).
NOTE
Adjusting the internal head amp gain between +17 dB and
+18 dB will internally turn PAD on/off. Noise may occur if
there is an impedance difference between the Hot and Cold
of a device connected to the [INPUT] connectors while
phantom power is being used.
!2 Cooling vent
The MTX3 contains a cooling fan. The cooling air is
exhausted here, so please be careful not to block this vent.
You must set this to the “UNIT ID” position the first time
you connect this device to a computer after purchase. If
you subsequently want to specify the IP address instead
of using the UNIT ID, specify the IP address from MTX
Editor and then switch this setting to the “PC” position.

Various Procedures
Recalling (switching) presets
Using the scheduler
With the MTX system, input/output port patching, matrix mixer
settings, and the parameters of XMV amps within the same
MTX system are stored together as a “preset” in the MTX3 and
in MTX Editor for recall when desired.
Each MTX system can store 50 presets. MTX Editor is used to
edit presets.
The scheduler can switch presets or play music and sound
effects from the SD memory card at the date and time you specify. Each such setting is called an “event.”
Event settings are made in the “Scheduler” dialog box of MTX
Editor. For details on operation, refer to “MTX Editor User’s
Manual.”
Each preset contains settings such as the following.
< Example 1 >
Switching background music and playback area

Various Procedures
Connecting via the [GPI] connector
GPI (General Purpose Interface) devices can be connected to
the rear-panel [GPI] connectors. GPI allows a variety of control
signals to be exchanged with external controllers or other
devices.
• Connection examples using the [GPI IN] connector
Example: Controlling the MTX3 from a switch box
MTX3
+5VDC
+V
CPU
IN
A/D
100k
The MTX3 provides 8 input ports and 4 output ports.
• The +5VDC terminals have an output voltage of 5V. The
maximum current draw is 100 mA total for the two terminals. If you are using a switch/variable resistor and an LED/
relay simultaneously, connect one terminal to the switch/
variable resistor and the other terminal to the LED/relay.
• The [IN]-1–7 terminals detect voltage changes from 0V to
5V. The [IN]-8 terminal alone supports +24V input; voltages in the range of 2.5–24V are detected as High, and voltages below 2.5V are detected as Low.
• The [OUT]-1–4 terminals are open collector outputs; they
will change between open or closed (Ground). The maximum voltage that can be applied is +12V. The maximum
current draw is 75 mA per port.
The GPI controller parameters are assigned via the MTX Editor
application.
Euroblock plugs (16-pin) are used for connections to the [GPI]
connector. For details, refer to “Euroblock plug connection” on
